Using Two-frequency Dust Spectral Matching to Separate Galactic Synchrotron and Free–Free Temperature Foregrounds from the Cosmic Microwave Background

Using Two-frequency Dust Spectral Matching to Separate Galactic Synchrotron and Free–Free Temperature Foregrounds from the Cosmic Microwave Background

We introduce a method for removing cosmic microwave background (CMB) and anomalous microwave emission (AME, or spinning dust) intensity signals at high to intermediate Galactic latitudes in temperature sky maps at frequencies roughly between 5 and 40 GHz. The method relies on the assumption of a spa...
